I just had a missed call from this number too and I have tried to call it back and am unable to get through. Strange.

I got it too. Fearing something dodgey, ( a phishing scam for example) I called it from a land line phone and got nothing. I would refrain from calling this number from your mobile phone. Hope I have helped.

Got call just now on my 3 mobile from (03) 8102 4400.
Didnt answer.

Same issues as Sal and Peter.

this number is calling me, but when i try to return the call operator says the line is disconnected?.

I just got it - have had it call my mobile before. Rang it from landline, it comes up as disconnected
